Do they fit you
Do you get blisters on your hands or rub the skin off at the thumb joint. If you normally have these types of injuries to your hands the bars are the wrong or incorrect bend for you. My son and I used a number of different bar bends and shapes based on our own selection and at the recommendation of others before we found one that works for us. We both use cotton gloves like FOX Paws and have no problems with our hands.
The old tried and true method of finding bars that are right for you. Sit on your bike in your normal riding position. Not the position that you comfortably sit on it casually in your garage, the way you sit when riding. Hold your hands and arms above your head. Close your eyes. Let your arms and hands fall naturally towards the bars. See where your hands land. If the palm of your hand does not fall on the hand grip portion of the bar, adjust the bars forward or back until your palm lands on the bar. Remember when you ride you typically hold your elbows out from your body. Your arm should have a slight down angle from your elbow to the wrist. Now close your hand around the bar in your normal grip. Does your hand extend straight from your wrist or is it at a little bit of an angle right or left. If it's at a large angle, the bars are not the correct bend. Your hands should extend straight out from your wrist. If this is not the case, it could be the bend of the bars, or that they are to wide or to narrow. If the bars are to wide or to narrow you should have determined that in the first step. Again, what is the angle of your hand to your wrist /arm? The top of your hand should be straight or a near straight extension of your arm.
You want to spread the pressure equally across the palm of your hand. If when you ride, you find blisters in select areas or skin being worn off due to friction or abrasion, the bars are not the correct bend for you. Undue pressure is being put on the effected areas. If your wrist is at to much of an angle it will tire quickly and arm pump and fatigue will occur because of the acute angle your wrist is at during most of your riding time. If you spend most of your riding time standing, it will make a difference in selecting the correct bars. You need to go through the routine in your normal standing position. Start by sitting and find the correct bar width and then stand to determine the correct bend.
I didn't say it would be easy. Fortunately I've been able to sell all the test bars. If you have buddies that will loan you a set of bars that makes it better. Or you can try their bikes if they're the same make and model as yours to see if the bar selection will work for you. There is no perfect bar bend that will work for both standing and sitting. Determine which you do most and pick the bend to best suit that. You should not be in the alternative riding position long enough for it to adversely effect you. If you are, you need to re-think your selection.
